Technical Field

[0001] The present application relates to the field of railway control equipment, and in particular to a turnout switching device. Background Art

It has the advantages of efficient switching, reliable locking, strong stability and durability, etc., and is therefore widely used in railway systems.

[0003] During operation, traditional turnout switching devices need to be regularly inspected, and their internal pipelines, metal wiring contacts and mechanical structures need to be maintained. In particular, the lubrication of the mechanical mechanism is required to ensure adequate lubrication in some harsh working environments such as extreme cold, high temperature, frozen soil, etc. to ensure the normal operation of the turnout switching device.

[0004] However, compared with normal working conditions, the effective time of lubrication under severe working conditions will be shorter and the probability of lubrication system failure will be greater. Therefore, maintenance will need to be more frequent, which will undoubtedly increase maintenance costs, and in harsh environments, the difficulty of maintenance will also increase.

[0005] Therefore, how to reduce the maintenance frequency and maintenance cost of turnout switching devices in severe weather is a problem that needs to be solved at present. Utility Model Content

[0025] Preferably, the temperature sensor is configured as an infrared sensor.

[0026] By adopting the above technical solution, the infrared sensor has the advantages of fast response speed, high measurement accuracy, and no need for direct contact with the mechanical mechanism.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1 This application is described in further detail.

[0035] The embodiment of the present application provides a turnout switching device, which mainly includes an electro-hydraulic switch machine, a switching lock and an automatic lubrication mechanism 1. This device integrates the automatic lubrication mechanism 1 to solve the problem of frequent lubrication and high maintenance cost of traditional turnout switching devices in harsh environments.

[0036] Specifically, the automatic lubrication mechanism 1 includes a storage container 11, an oil pump 12 and an oil pipeline 13. The storage container 11 is used to store lubricating oil, and its design capacity is sufficient to meet long-term working requirements. The oil pump 12 is responsible for pumping the lubricating oil from the storage container 11 to the oil pipeline 13, and the oil pipeline 13 further extends to the mechanical mechanism of the electro-hydraulic switch and the conversion lock, providing continuous and stable lubrication for these key parts.

[0037] Furthermore, a liquid level meter 14 is provided on the storage container 11, and the liquid level meter 14 is connected to the main control board 3 for real-time monitoring of the lubricating oil reserve in the storage container 11. When the lubricating oil reserve is lower than a preset safety threshold, maintenance personnel can replenish the lubricating oil in time, thereby ensuring the continuous and stable operation of the lubrication system.

[0038] In addition, the storage container 11 is also equipped with an electric heater 15. In an extremely cold environment, the electric heater 15 can continuously heat the lubricating oil in the storage container 11 to keep it at a constant temperature. This not only improves the fluidity of the lubricating oil, but also ensures that the lubricating oil can always maintain the best lubricating effect in a harsh environment, and facilitates the storage of the lubricating oil.

[0039] The electric heater 15 specifically includes a heating element 151 and an electric thermostat 152. The heating element 151 is electrically connected to the electric thermostat 152, and the electric thermostat 152 is communicatively connected to the main control board 3. The electric thermostat 152 can adjust the working power of the heating element 151, thereby adjusting the heating temperature.

[0040] A nozzle and an electromagnetic switch valve are provided at the oil outlet of the oil delivery pipe 13. The design of the nozzle enables the lubricating oil to be sprayed onto the mechanical mechanism in a more uniform and delicate manner, thereby improving the lubrication effect. The electromagnetic switch valve is electrically connected to the main control board 3 to achieve precise control of the lubricating oil supply. When the main control board 3 determines that increased lubrication is needed based on the temperature data, the flow rate of the lubricating oil will be increased by controlling the opening of the electromagnetic switch valve.

[0041] At the same time, a hydraulic sensor 16 is also added to the oil pipeline 13. The hydraulic sensor 16 is connected to the main control board 3 for real-time monitoring of the pressure changes inside the oil pipeline 13. When the oil pipeline 13 is damaged or other reasons cause the pressure inside the oil pipeline 13 to be abnormal, the main control board 3 will send a signal to remind the staff, so that the staff can inspect and repair the automatic lubrication mechanism 1, thereby ensuring the safe and reliable operation of the entire mechanism.

[0042] In order to accurately detect the lubrication condition of the mechanical mechanism of the electro-hydraulic switch and the conversion lock, a temperature sensor 2 is provided at the mechanical mechanism, and the temperature sensor 2 is used to monitor the temperature of these parts in real time. The temperature data is transmitted to the main control board 3 in real time through the communication connection. The main control board 3 analyzes and processes the temperature data according to the preset algorithm, and automatically controls the operation of the oil pump 12 according to the processing result. For example, under normal circumstances, when the temperature at the mechanical mechanism is higher than the set threshold, it will be determined that the mechanical mechanism lacks lubrication. At this time, the main control board 3 will start the oil pump 12 to increase the supply of lubricating oil to ensure that the mechanical mechanism maintains a good lubrication state.

[0043] In the embodiment of the present application, the temperature sensor 2 is an infrared sensor, which has the advantages of fast response speed, high measurement accuracy, and no need for direct contact with the mechanical mechanism. It can more accurately reflect the actual temperature conditions of the mechanical mechanism and will not interfere with the normal operation of the mechanical mechanism.

[0044] A wireless communication module 31 is also provided on the main control board 3. Through the wireless communication module 31, the main control board 3 can upload key information such as temperature data, liquid level data and oil pressure data to the remote monitoring center in real time. This enables maintenance personnel to grasp the working status of the turnout switching device anytime and anywhere, and timely discover and deal with potential problems, thereby further improving the operation and maintenance efficiency of the entire system.

[0045] The implementation principle of this embodiment is: by integrating the automatic lubrication mechanism 1 and the intelligent control system, continuous and stable lubrication of the key parts of the turnout conversion device is achieved. At the same time, by introducing a variety of sensors and the main control board 3, accurate control of the lubrication process and real-time monitoring and remote transmission of key data are achieved. This not only reduces the maintenance frequency and cost in bad weather, but also improves the stability and reliability of the entire system.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
